The probiotic strain LA-5® originates from our collection of dairy cultures at Chr. Hansen. It is safe for human consumption; it has been granted QPS1 (Qualified Presumption of Safety) status in Europe. It has been used in food and dietary supplements since 1979.
LA-5® is considered a comprehensively documented probiotic strain as it has been reported in more than 150 scientific publications. More than 60 of these publications reported LA-5® data from clinical trials which had been conducted across numerous areas of health, primarily in combination with Bifidobacterium, BB-12®. These studies predominantly focused on adults and the elderly.
LA-5® and BB-12® are registered trademarks of Chr. Hansen A/S.
At Chr. Hansen, our strains are backed by science. All of our probiotic strains are supported by clinical documentation. Learn more about the beneficial effects our strains have on different health areas.
